BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a magazine, and more particularly to amagazine which is disposed with an air cartridge.

2. Description of the Prior Art

A conventional air gun includes a magazine for loading bullets, thebullets are fired by releasing a compressed air.

Said compressed air can be from an external device, such as an aircompressor, which can provide a compressed air to project a bullet. Theexternal device can provide stable and strong air pressure for the airgun, but the external device cannot be carried.

Further, said compressed air can be from an internal device, such as anair cartridge, which is disposed to the air gun. Therefore, the air guncan be portable. Some conventional air guns are equipped with an aircartridge in its magazine, as shown in TWM358289, wherein its FIG. 3 andFIG. 7 both disclose that an air cartridge is fixed to the bottom of themagazine. However, the means of fixing the air cartridge increases thevolume of a gun, and changes a centroid of the gun, so that thestability of the gun is affected. Moreover, the air cartridge is easy tofall off from the magazine when the gun is impacted, and the aircartridge may be projected out by the remaining pressure in the aircartridge when a user unloads it. Furthermore, the FIG. 11 of saidpatent discloses that the air cartridge is put into a lateral recess ofthe magazine. The air cartridge is then fixed by an elastic piece, butthe elastic force is not strong enough to firmly abut against the aircartridge. As a result, the air cartridge is likely to fall off if theuser inadvertently hits the magazine or the magazine is hit with alateral force.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a magazine inwhich an air cartridge can be tightly fixed.

To achieve the above and other objects, a magazine of the presentinvention includes a main body and a plug member. The main body isformed with a trough and a recess. The trough is provided to receivebullets. The recess has a lateral opening, a top portion and a bottomportion. The recess is used for abutting an air cartridge between thetop portion and bottom portion. The lateral opening is used for the aircartridge being put therethrough, and the main body further comprises ahole. The hole passes through the bottom portion and communicates withthe recess. A diameter of the hole is smaller than a maximum diameter ofthe air cartridge. The plug member is screwed into the hole so as topress the air cartridge toward the top portion.

Thereby, the plug member gradually presses the air cartridge by screwaction. Once the plug member is completely screwed into the hole, theair cartridge does not fall out from the recess.

The present invention will become more obvious from the followingdescription when taken in connection with the accompanying drawings,which show, for purpose of illustrations only, the preferredembodiment(s) in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1 to FIG. 3 for a preferred embodiment of thepresent invention. A magazine of the present invention includes a mainbody (10), a plug member (20), a base (30), an anti-slide member (40),an elastic member (50), a support member (60), and a rod (70).

The main body (10) is formed with a trough (11), a recess (12), a hole(13), a groove (14) and a limit hole (16). The trough (11) is used forreceiving bullets. The recess (12) has a lateral opening (121), a topportion (122), and a bottom portion (123). The recess (12) is providedto receive an air cartridge (1) between the top portion (122) and thebottom portion (123). The lateral opening (121) is used for the aircartridge (1) being put therethrough. The hole (13) passes through thebottom portion (123) and communicates with the recess (12). A diameterof the hole (13) is smaller than a maximum diameter of the air cartridge(1). In other words, the air cartridge (1) cannot pass through the hole(13) and then fall off from the recess (12). The groove (14)communicates with the trough (11). Preferably, an opening end isrespectively formed at the bottom of the trough (11) and the groove(14). An axial direction of the limit hole (16) is vertical to alongitudinal direction of the trough (11), and the limit hole (16)communicates with the trough (11).

The plug member (20) is screwed into the hole (13) so as to press theair cartridge (1) toward the top portion (122) of the recess (12).Preferably, the plug member (20) includes a first end and a second endopposite to the first end. The first end is formed with an abuttingsurface (21) for abutting the air cartridge (1). Preferably, theabutting surface (21) is formed as a shape corresponding to a bottom ofthe air cartridge (1). In the present embodiment, the abutting surface(21) is formed as a concave surface so as to completely abut against thebottom of the air cartridge (1). The second end is formed with a drivingportion (22). The driving portion (22) can be formed as a polygonalcolumn as shown in the FIG. 1, or as a polygonal hole, or a knob havinga granular surface. In this way, the plug member can be rotated by handor with a tool.

The base (30) is slidably disposed with respect to the main body (10).One of the base (30) and main body (10) is formed with at least oneslide rail, and the other one of the base (30) and the main body (10) isformed with at least one slide chute. Thereby, the base (30) and themain body (10) can slides with respect to each other. In the presentembodiment, the base (30) has two parallel arms (31). The base (30)further comprises a pair of slide rails (32) which is respectivelylocated on an inner side surface of each of the arms (31). And thebottom of the main body (10) is disposed with a pair of slide chutes(15) corresponding to the rails (32). To prevent the plug member (20)from getting loose or being inadvertently slid out of the main body whenreloading bullets, a sliding direction of the base (30) with respect tothe main body (10) is unparallel to an axial direction of the hole (13).Preferably, the sliding direction is vertical to the axial direction ofthe hole (13), and at least one part of the base (30) covers at leastone part of the driving portion (22). In the present embodiment, thearms (31) are used for clamping two sides of the driving portion (22).In other possible embodiments of the present invention, the base canfurther comprise a bottom plate so as to completely cover the drivingportion (22). Further, the base (30) can be formed with a pin-hole (33)on its top, as shown in FIG. 3.

The anti-slide member (40) selectively couples to the base (30) so as toprevent the base (30) from sliding with respect to the main body (10).Preferably, the anti-slide member (40) is formed with a pin (41) on itsbottom, and the pin (41) is used for selectively being inserted into thepin-hole (33). Consequently, the anti-slide member (40) couples to thebase (30). Moreover, the support member (60), the elastic member (50),and the anti-slide member (40) are put through the opening end to thetrough (11) one after another. The support member (60) is adapted topush the bullets in the trough (11) to a gun bore through anotheropening on another end of the trough (11). Two sides of the elasticmember (50) respectively abut the support member (60) and the anti-slidemember (40), so that the support member (60) has a tendency of movingtoward the another opening of the trough (11), and the anti-slide member(40) has a tendency of moving toward the base (30), and the pin (41) canautomatically be inserted into the pin-hole (33). One side of theanti-slide member (40) is disposed with a pair of notches (42)corresponding to the limit hole (16). Another side of the anti-slidemember (40) is laterally formed with a convex portion (43). The convexportion (43) can slightly aslant penetrates through the groove (14), sothat a user can slide the convex portion (43) to move the anti-slidemember (40). Each of the notches (42) has a first notch end (421) and asecond notch end (422). The rod (70) is inserted into the limit hole(16) and the notches (42) and selectively abuts against between thefirst and the second notch end (421, 422). Thereby the sliding of theanti-slide member (40) is limited, and the anti-slide member (40) doesnot come off the trough (11) by the push of the abutting member (50).

As shown in FIG. 4 and FIG. 5, the magazine of the present invention canbe disposed into an air gun (2). The air cartridge, which is not fixedoutside of the air gun (2), does not change a centroid of the air gun(2) or hinder the use of the air gun (2), or affect the appearance ofthe air gun (2). Preferably, a slide cover (3) of the air gun (2) can bemade of steel, so that the air gun (2) has stronger recoil that makesits auto-reloading process be smoother.

Accordingly, the plug member of the present invention gradually pressesthe air cartridge by screw action and then firmly fixes the aircartridge in the recess once the plug member is completely screwed intothe hole, so that the air cartridge does not fall off while shooting orreloading bullets. The remaining pressure in the air cartridge will begradually released as the plug member is unscrewed from the hole, sothat it is safe to detach the air cartridge. Furthermore, the basecovers the driving portion of the plug member so as to prevent a userfrom inadvertently sliding the plug member. Besides, the anti-slidemember selectively couples to the base, so that the base does not slideaway from the main body. And the rod is adapted to prevent theanti-slide member from coming off the trough by the elastic member.

In addition, to have stronger recoil, the bolt of the gun can be made ofsteel, so that it can also increase the rigidity and the weight of thegun.
